ive got an 85 SC with the DC top mount kit. im wanting to swap the car to 87 LM so it would easier tune (perferably ostrich box). is this possible and still be able to keep t1 log setup? do i still have to have 2 injectors (2&4 i belive) richer then the other 2 because of the log manifold runners if i put +20s in? ANY IDEAS????????
